What disruptive use cases are enabled by private 5G that weren't feasible with Wi-Fi or public 5G networks?

Autonomous AGVs and drones achieve deterministic low latency under 1ms with guaranteed quality of service, enabling real-time collision avoidance and precise positioning that Wi-Fi's variable latency cannot support.

Ultra-dense IoT deployments support over 1 million devices per square kilometer with per-device quality of service guarantees for industrial sensors, wearables, and control systems that would overwhelm traditional Wi-Fi infrastructure.

AR-powered maintenance and inspection deliver high-throughput, low-jitter video streams to headsets for overlaying digital schematics on physical equipment in harsh industrial environments where Wi-Fi signals degrade.

Neutral host architectures provide seamless multi-operator coverage in stadiums, airports, and large campuses by combining private and public networks without the complexity and cost of distributed antenna systems (DAS).

Mission-critical applications achieve carrier-grade reliability with 99.999% uptime and failover capabilities that public 5G networks cannot guarantee due to shared infrastructure and prioritization policies.

What are the current technological limitations or bottlenecks preventing broader deployment of private 5G?

Enterprise-grade 5G device ecosystems remain immature, with limited availability of industrial modems, modules, and ruggedized handsets specifically designed for private network environments.

Integration complexity across IT/OT systems, legacy infrastructure, and multi-vendor 5G stacks requires specialized expertise that most enterprises lack internally, creating dependency on costly system integrators.

Global spectrum fragmentation hampers cross-border private network deployments, as CBRS-like shared spectrum models haven't been harmonized internationally, creating licensing and compliance challenges for multinational enterprises.

High capital expenditure requirements for RAN hardware, core software licenses, and edge compute infrastructure create significant barriers for small-to-medium enterprises considering private 5G adoption.

Interoperability gaps between evolving O-RAN specifications and multi-operator core networks (MOCN) require extensive testing and validation, slowing deployment timelines and increasing integration risks.

Which startups in this space have recently raised funding, how much, and from whom?

Recent funding rounds demonstrate strong investor confidence in private 5G infrastructure and software platforms, with Series A and B rounds dominating the landscape.
